PUSH-BUTTON FOR REPEATlNG-WATCHES.

SPECIFICATION forming part of Letters Patent No. 367,995, dated August9, 1887.

Application filed November 30, 1886. Serial No. 220,257. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES MoRLn'r, of Jersey City, in the county ofHudson, State of New Jersey, have invented certain new and usefulImprovements in Push-Buttons for Bepeating-Vatches, of which thefollowing is a specification.

This invention has reference to a push button or slide-piece foractuating the sounding mechanism of repealing-watches, said slidv piecebeing capable of readyinsertion into the watch-case without requiringthe special fitting of the parts to thesame to each individual case; andthe invention consists of a push-button for repeating-watches which iscomposed of a slotted filling-piece of segmental shape that is solderedor otherwise attached toa corresponding recess of the watch-case center,of an exterior slide-piece having a nose for the finger, and an interiorslide-piece connected to the exterior piece by a screw, said interiorslide-piece being guided along a fixed are shaped arm of the main pieceand acted upon by a spiral spring interposed between thesupporting-socket ofsaid arm and the end of the interior slide-piece, aswill be fully described hereinafter, and finally be pointed out in theclaims.

In the accompanying drawings, Figure 1 represents a front elevation of arepeatingwatch with my improved push-button for operating the soundingmechanism of the same. Fig. 2 is a vertical longitudinal section of thepush-button shown inserted in the case and drawn on a larger scale. Fig.2 is a side View of the push-button shown as detached from the case; andFig. 3 isa vertical transverse sectio on line a; :c, Fig. 2.

Similar letters of reference indicate correspending parts.

Referring to the drawings, A represents the main or filling piece of myimproved push-bntton for repeatingwatches. The filling-piece A ismade-of segmental shape, and arranged to be inserted into a slot, a, ofcorresponding shape, which slot is arranged at any suitable point of thewatch-case center, as shown in Fig. 1. The main or filling piece A issoldered, screwed, or otherwise attached to the watch case center, so asto be firmly retained in the slot of the same. The filling-piece Ais-provided at its middle part with a slot, a, which slot serves toguide a screw, (2, that connects the exterior slide-piece, B, with theinterior slide-piece,(), which together form the pushbutton of therepeating attachment of the watch. The exterior slide-piece,B,isprovided with a projection or nose, (1, against which the finger isplaced when actuating the push-button and repeating device. The innerslidepiece, 0, is provided with a perforated lug, b, at one end andguided along a fixed arc-shaped arm, f, that is attached to a fixedsocket, f,of the main piece A. A spiral spring, g, is placed on theguide-arm f and interposed between the socket f and the perforated endlug, b, of the inner slide-piece, C, said spring serving to return theslidepieces B and C and the connecting-lever of the repeating attachmentto their normal positions as soon as the pressure of the finger on theexterior slide-piece is relaxed. By pushing the exterior slide-piecewith the finger the spiral spring g is compressed until theconnecting'screw d arrives at the end of the slot c,the spring returningthe slide pieces into their normal position on returning into itsexpanded condition.

My improved push-piece or slide-button for repeating-watehes has theadvantage that it can be conveniently fastened and inserted into thecenters of watch-cases without the loss of time required in attachingthe parts of the push-button to the watch-case center, as was requiredby the practice heretofore in use.

In case any part of the push-button should get out of order, it canbereadily detached from the case,so as to be repaired in a convenientmanner, without interference with the movement. \Vhen the movement withthe repeating attachment is inserted into the ease, the actuating-leverof the attachment is attached in any approved manner to the interiorslide-piece,O,of the push-button, as indicated in dotted lines in Fig.2, and detached from said slide-piece when the movement is to be removedfrom the case for repairs or otherwise.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A push button for repeating-watches, con sistingof a slotted mainor filling piece, an

interior spring-actuated slide-piece, an exterior slidepieee, and ascrew [or connecting said slide-pieces, substantially as set fortlr 2. Apush-button for repeatirig-watches, consisting of a slotted main orfilling piece, an exterior slide-piece having a projecting nose, aninterior slide-piece, a screw connecting the exterior and interiorslide-pieces, an areshaped guide-arm passing through the perlo rated endof theinnerslide-piece, and a spiral springloeated on said arm andacting on said interior slide-piece, substantially as set forth.
